[UCLASS](Programming/UnrealArchitecture/Reference/Classes#classdeclaration)(BlueprintType) class UGPULightmassSettings : public [UObject](API\Runtime\CoreUObject\UObject\UObject)
bool
bCompressLightmaps
Whether to compress lightmap textures.
bool
bShowProgressBars
If true, draw a green progress bar within each tile as it renders.
bool
bUseFirstBounceRayGuiding
If Irradiance Caching is enabled, First Bounce Ray Guiding will search the hemisphere over each first bounce sample to find the brightest directions to weigh the rest of the samples towards.
bool
bUseIrradianceCacheBackfaceDetection
Further prevent leaks caused by irradiance cache cells being placed inside geometry, at the cost of more fireflies and slower sampling speed. Recommended to be used with higher irradiance cache quality (>=256)
bool
bUseIrradianceCaching
Irradiance Caching should be enabled with interior scenes to achieve more physically correct GI intensities, albeit with some biasing.
bool
bVisualizeIrradianceCache
If true, visualize the Irradiance Cache cells.
EGPULightmassDe...
Denoiser
EGPULightmassDe...
DenoisingOptions
If enabled, denoise the results on the CPU after rendering.
int32
FirstBounceRayGuidingTrialSamples
Number of samples used for First Bounce Ray Guiding, which are thrown away before sampling for lighting.
int32
GISamples
Total number of ray paths executed per texel across all bounces.
float
IrradianceCacheCornerRejection
Reject IC entries around corners to help reduce leaking and artifacts.
int32
IrradianceCacheQuality
Number of samples per Irradiance Cache cell.
int32
IrradianceCacheSpacing
Size of each Irradiance Cache cell. Smaller sizes will be slower but more accurate.
int32
LightmapTilePoolSize
GPU Lightmass manages a pool for calculations of visible tiles.
EGPULightmassMo...
Mode
Full Bake mode renders the full lightmap resolution for every object in the scene.
int32
StationaryLightShadowSamples
Number of samples for stationary shadows, which are calculated and stored separately from GI.
int32
TilePassesInFullSpeedMode
Baking speed multiplier when Realtime is disabled in the viewer.
int32
TilePassesInSlowMode
Baking speed multiplier when Realtime is enabled in the viewer.
int32
VolumetricLightmapDetailCellSize
Size of an Volumetric Lightmap voxel at the highest density (used around geometry), in world space units.
